A painstakingly annoted copy of the work De natura animalium tractatus XIX by Aristotle, in the Latin version by the scholar Michael Scotus († ca. 1235), written during the 13th century, with an opening "I" initial, partly decorated in gold, showing a man sitting before a book. In 1453 this manuscript was owned by one Johannes Kalf from Wangen (in Allgäu); bound in a Kopert (limp vellum) binding. (smu)
